Boxers come from late nineteenth-century Germany, where the Bullenbeisser, a hunting dog used to hold boar and deer, was crossed with English Bulldogs. The result is a square, muscular working dog with a short, shiny coat in fawn or brindle, often with white markings and a black mask. That thin coat sheds lightly and needs little grooming, but it offers little protection from cold.
Many Boxers are clownish, affectionate and physical, and they tend to stay puppyish for years. In Brooklyn, that means planning for daily exercise, patient reward-based training and some care on stoops and crowded sidewalks, where a strong, bouncy dog can pull or knock into people. Dogs of the breed vary, and many Boxers listed for adoption are mixes, so each dog's size and energy can differ from the description.
